Abstract

PURPOSE:To enable a cooling capacity to be freely set under an increased number of or decreased number of a freezer devices in response to a freezing productivity of foodstuff by a method wherein a tunnel type freezer is constructed through a connection of a plurality of freezer devices which can be freely installed or demounted. CONSTITUTION:A freezer device is constructed by a plurality of short and small freezers 1a. These freezers 1a are abutted and connected through connector means in such a way as they may be freely installed or demounted in their longitudinal directions. As the connector means, they are constructed by a reinforcing body 1b of which inner sides of each of the freezers 1a are assembled into a cubic frame structure, resulting in that a coupler plate 1c is abutted to cover an abutment part 1c of the adjoining members 1b, they are fixed by some fastener members 1d such as bolts and nuts and then the freezer devices 1a are connected to each other. The coolers are classified into some groups for every freezer, a freezer is separately connected to the cooler of each of the groups and only the required number of devices can be operated when a load is decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a food freezing device, particularly a tunnel type freezing device.

[Prior Art] A conventional food freezing device of this type is one in which a food transfer conveyor is inserted into a tunnel-shaped freezer with a built-in cooler and moves from a wide opening at one end to an exit at the other end. It is being

[Problems to be Solved by the Invention] The conventional food freezing device described above transfers the food from the inlet side of one end of the freezer to the outlet side of the other end by moving a conveyor, and during this time, the food is completely frozen by contact with the cold air of the cooler. Since the length of the freezer and the cooling capacity inside the freezer are set in advance, in other words, the freezing production capacity is fixed, so there may be times when you want to increase productivity beyond this capacity. However, this is not possible, and in the past, when it was necessary to increase productivity, the extremely uneconomical method of remanufacturing a new long freezer with a large freezing production capacity had to be taken. It's something that didn't exist.

On the other hand, there are cases where it is desired to reduce productivity below the freezing production capacity of the above equipment, but since the freezing capacity is originally fixed, it is not possible to lower this freezing capacity, and as a result, the There is also the problem that power is wasted.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention aims to provide a food freezing device that can freely set the corresponding cooling capacity when it becomes necessary to increase or decrease freezing productivity. That is.

[Means for Solving the Problems] To achieve the above object, the present invention provides a refrigerator in which a food transfer conveyor that moves from the entrance side of one end to the exit side of the other end is inserted into a tunnel-type freezer with a built-in cooler. The gist of the apparatus is a food freezing apparatus, characterized in that the freezer comprises a plurality of storage units that are provided with connection means and can be attached and detached in the longitudinal direction via the means. [Embodiment 1 is a horizontally long tunnel type freezer, and one end of this freezer 1 is provided with a population 2, and the other end is provided with an outlet 3. Also,
A plurality of coolers 5 supported by a machine frame 4 that can be inserted into the freezer 1 are inserted into the freezer 1, and a net conveyor 6 suspended from the machine frame 4 is installed below the coolers 5. The conveyors 6 are opposed to each other with a required transfer space in between, and are configured to move from an inlet 2 at one end of the freezer 1 to an outlet 3 at the other end. The coolers 5 are each connected to a refrigerator 5a installed outside the freezer 1, and a cold air stirring fan 7 is inserted into the cooler 5.
It is connected to a motor 8 attached to the ceiling wall. Further, as shown in FIG. 7, a liquid injection nozzle 9 for cleaning the inside of the freezer 1 is provided at the upper part of the inside of the freezer 1, and a liquid injection nozzle 10 for cleaning the cooler is provided for the cooler 5. At the exit of the conveyor 6, there is a conveyor A, through which the conveyor 6 is immersed.
A cleaning tank 11 is provided, and various chemical tanks 12 . The fresh water tank 13 is a switching valve 14. This is a schematic configuration of this type of food freezing device, in which a waste water storage tank 16 and a drainage pump 17 communicating with the storage tank 16 are connected to each other via water pumps 15, and are connected to the bottom of the freezer 1. .

Therefore, the gist of the present invention is that the freezer 1 is constituted by a plurality of short and small storage units (Ia), and these storage units (Ia) are butted and connected removably in the longitudinal direction via a connecting means. It is something.

In this example, the connection means shown in FIG. 3 is used.

As shown in Fig. 4, each storage unit 1a is composed of a reinforcing frame 1b assembled into a rectangular cubic frame with a frame inside.
Although we have shown an example in which the joint plates 1c are placed along the butt portions 1c of the adjacent frames 1b and fastened with the tightening members 1d such as bolts and nuts to connect the storage unit (1a) to each other,
Of course, it is not limited to this example.

Further, in this example, the coolers 5 are divided into groups for each storage unit, and refrigerators are individually connected to the coolers in each group, so that only the necessary number of refrigerators can be operated when the load is reduced.

Therefore, in order to facilitate cleaning of the freezer 1 configured by connecting the storage unit 1a, the present invention divides the freezer 1 into an upper storage unit A and a lower storage unit B, and separates the upper storage unit 1a. A
Lifting device 1 provided on the entrance 2 side and the exit 3 side of the freezer 10
8 for horizontal lifting.

In this example, the lifting device 18 is a so-called electric screw jack that connects a rotary screw 20 to a motor 19 and raises and lowers the upper storage body A by rotating the screw 20 in forward and reverse directions. However, it is not limited to this, and hydraulic or pneumatic jacks may also be used.

[Function] Food is placed on the conveyor 6, and as the food is transferred from the outlet 2 at one end of the freezer 1 to the outlet 3 at the other end by the movement of the conveyor 6, it comes into contact with the strong cold air released from the cooler 5. The frozen food is then sequentially frozen, and the frozen food is taken out from the outlet 3.

On the other hand, when the food is frozen, oil and residue from the food adheres to the inner surface of the freezer 1, and if this is to be cleaned, the upper storage body A
Pressurized water is sprayed from nozzle 9 and 10 while the nozzle remains closed to clean it.

There are cases where firmly attached oil and scum cannot be thoroughly washed away by only the above-mentioned jet of pressurized water. In such a case, the lifting device 18 is driven to lift the upper storage body A as shown in FIG. By inserting a brush or the like and washing by hand, you can completely remove stubborn oil and residue.

After the above-mentioned cleaning, the lifting device 18 is reversely driven to remove the upper storage body A.
By lowering it again as shown in FIG. 1, the dividing surface of the upper storage body abuts against the dividing surface of the lower storage body B, and the normal tunnel-type freezer is restored.

[Effects of the Invention] In short, according to the present invention, since the tunnel-type freezer is configured by connecting a plurality of removable storage units, it is possible to add storage units or to You can freely set the cooling capacity by reducing the
One model can support any freezing productivity.

Therefore, it eliminates the uneconomic problem of having to rebuild a new freezer with a capacity that corresponds to the increase in freezing productivity, which was the case in the past. Since it can be lowered freely, it has excellent features that cannot be desired in conventional tunnel type refrigeration equipment, such as eliminating the problem of wasting power for driving the compressor.
